Re: perpendicular split pane control (3 panes: 1 vertical, 2 horizontal)

Hi All;

The "standard" in Java/Swing and Microsoft's UI toolkit [and 
IBM's guidelines] appears to be pressing the F6 moves between 
panes and pressing F8 gives focus to the Splitter Bar itself. 
 From there, the user interacts with the up-down, left-right 
movement depending on whether the splitter bar is an up-down or 
left-right type of splitter.

A question for the list: Can't these key sequences be used? If 
they can't, why?
